Tim found a tool in his father's toolbox and was curious about what it is used for.
what does this tool do?

a. measure length
b. meausre volume
c. measure mass
d. measure temperature

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

When solid surfaces slide over each other the kind of friction that occurs is called friction

Hi , i am new here can anyone me out with this question why is space black after having so many shining objects like sun , moon , stars
